Its a slow but a realy interesting sci fi movie. After the 6.th epizode im realy waiting the next one. But if you are looking a sci fi like battle los angeles or edge of tomorrow (anyway they was also great, but different) its not this. Here the people with the negative review are waiting an action movie, becouse thay think every sci fi has to be a action movie as you will see when you read them. But not every sci fi is action movie. At least the best ones are not. There is solaris, there is space odissey ect... give a shot. Its a good one. Even if actionmans are dont understand.
